TSM1011AID

Overview

The TSM1011AID is a highly integrated constant voltage and constant current controller designed for switch-mode power supply applications. It features an operating temperature range from 0°C to 105°C and utilizes an SO-8 package. The device integrates a fixed 2.545V voltage reference with 1% precision and two operational amplifiers with ORed outputs. It supports low voltage operation, offers 2 kV ESD protection, and includes a current sink output stage for easy compensation.

Feature Summary

• Integrates constant voltage and constant current control modes within a single solution
• Features a fixed 2.545V voltage reference with high precision
• Provides 2 kV electrostatic discharge protection
• Utilizes a current sink output stage for simplified circuit compensation

Applications

• Switch-mode power supply (SMPS) designs requiring combined CV and CC modes
• Battery charging systems needing precise voltage and current regulation
• Adapters and chargers utilizing low external component counts

Procurement Notes

Verify the specific suffix 'AID' corresponds to the industrial grade and SO-8 package configuration. Confirm that the 1% voltage precision matches the design requirements, as other variants may offer different tolerances. Ensure the operating temperature range of 0°C to 105°C aligns with the thermal constraints of the target application environment before finalizing procurement.

Selection Notes

Select this component when a unified solution for both constant voltage and constant current regulation is required in SMPS architectures. The integration of the voltage reference and dual operational amplifiers reduces external component count compared to discrete solutions. Consider the SO-8 package size and the 2 kV ESD rating for robustness in sensitive power management circuits.
